[PATCH] i2c: sh_mobile: Fix compilation warning

[Viresh Kumar]

This currently generates a warning:

drivers/i2c/busses/i2c-sh_mobile.c: In function 'sh_mobile_i2c_isr':
drivers/i2c/busses/i2c-sh_mobile.c:399:26: warning: 'data' may be used 
uninitialized in this function [-Wmaybe-uninitialized]

Though the code looks okay and shouldn't ever use the variable
uninitialized.

Fix the warning by moving the code around and getting rid of 'data'.

Compile tested only.
